In this application note, we provide an overview of smart speaker acoustic measurements with a focus on frequency response – the most important objective measurement of a device’s audio quality.
A smart speaker is an internet-connected (usually wireless) powered speaker with built-in microphones that enables you to interact with an intelligent virtual assistant (IVA) using voice commands. IVA technology, partnered with microphones and loudspeakers to support it, is being added to all sorts of devices like refrigerators, microwave ovens and set top boxes, enabling voice control of those devices.
Testing the overall end-to-end performance of a smart speaker’s primary input and output audio paths can be quite challenging. In this application note, we provide an overview of smart speaker acoustic measurements with a focus on frequency response.
